protected member function
ostream& operator= (const ostream&) = delete;
ostream& operator= (ostream&& rhs);
Exchanges all internal members between rhs and
*this, except the pointers to the associated stream buffers: rdbuf shall return the same in both objects as before the call.
This is the same behavior as calling member ostream::swap.
Derived classes can call this function to implement move semantics.
- Another ostream object.
Modifies both stream objects (
*this and rhs).
No-throw guarantee: this member function never throws exceptions.
- Swap internals (protected member function
